Defect maintenance of Penang Bridge / Noor Shuhaila Yaacob

Bridge form a vital link in any road/rail network. A bridge is meant for carrying vehicular traffic across rivers, structures for interchange including underpasses and flyovers across the highways/railways. Bridge deteriorating and consequent bridge failure can be considered both a technical and social problem and its needed maintenance to ensure that bridge is safe to use and well function. The maintenance work start from in the first stage of design of bridge which is to avoid defect may appear due to fault in design. There have many incidents that happened on bridge due to lack of maintenance on bridge which poor maintenance management because bridges are easier exposed to get defect due to the stresses on a bridge caused by traffic, weather, and construction can resulting cracks in structures of bridges. The objectives of this research are to identify on common and major defect of bridge, investigate the causes of defect on bridge, study the management and maintenance system of bridge, and recommend the best procedure and technique of maintenance and management for bridge defects. The objective of this study was achieved through research from various sources such as textbooks, journals, and etc that related to this research and this research was supported by closed observation, using photo that been taken and formal interviews. From the investigation and research that has been made, the common and major defect can be determined such as concrete. It occurred due to poor design and details, material specifications, construction and environment. Through by best procedure and technique of maintenance and management for bridge defects can ensure the bridge always wellmaintain and function.
